DISH-WASHING MACHINE.

Specification of Letters Patent.

Patented Jan. 10, 1911.

Application filed February 25, 1907. Serial No. 359,213.

To all whom it may concern:

Be it known that I, ANGELO PANASGI, a subject of the King of Italy, residing at Philadelphia, in the county of Philadelphla and State of Pennsylvania, have invented certain new and useful Improvements in Dish-\Vashing Machines, which improve ments are fully set forth in the following specification.

This invention relates to improvements in constructions of that class commonly known as dish-washing machines, the same being availed of for subjecting dishes and similar utensils to a cleansing operation.

The object of this invention is to provide a dish-washing machine which shall be simple, compact and inexpensive as regards construction; durable, efficient, speedy and reliable in practical service; which shall embody novel features of construction whereby, and when desired by the user, the opposite sides of a dish, or similar utensil, may be directly and uniformly treated at one and the same time; which shall be convenient in its application to practical purposes; and which shall possess certain well-defined advantages over prior analogous constructions.

The invention consists in the novel combinations, details and parts whereby, together with the novel relative disposition of said parts, the attainment of the foregoing object is rendered practicable, all of which will be more specifically referred to hereinafter and set forth in the appended claims.

The invention is clearly illustrated in the accompanying drawings, wherein like reference-numerals denote corresponding parts throughout the several views, and as to the latter:

Figure 1 is a front elevation of a dishwashing machine embodying my said improvements. F 2 is a central, vertical section of same, as along the line a:ac of Fig. at. Fig. 3 is a side elevation of same, with outer side bearing-piece removed. Fig. t is a plan view thereof, a portion of the top cross piece being broken away. Fig. 5 is a detail perspective view showing detached the dish-carrier which I purpose making use of. Fig. 6 is a detail view show ing features of construction whereby the wipers made use of are each replaceably conjoined with its actuating shaft.

In a general sense my present invention comprises a rotatable wiper; means for actuating the same; and a dish-carrier, the latter movable into and out of the plane of movement of said wiper.

It further comprises in a general sense, a pair of wipers facing each other and rotatable in adjacent, parallel planes; means for jointly actuating said wipers; and a dish-carrier, the latter movable simultaneously into and out of the respective planes of movement of said wipers.

In carrying out my invention, reference being had to the accompanying drawings, I make use of a tank, having uprights 2, 3, rising therefrom at opposite sides thereof, and connected at their upper ends by a crosspiece 4, a similar cross-piece 5, arranged parallel with the cross-piece 4, beneath the same and spanning said tank, by preference interiorly thereof, being employed, these parts being relatively secured in position in any common and well known manner, and so as to give substantial rigidity to the frame structure thus formed.

6 denotes a primary wiper-shaft, projecting downwardly through, and terminating somewhat below, the cross-piece at, with respect to which said shaft is movable both rotarily and longitudinally. As an additional bearing for the shaft 6, and to insure the steady movement thereof with respect to a definite axis, I provide a bracket 7, secured to and projecting inwardly from the upright 2. There is replaceably conjoined with the wiper-shaft 6, at its lower eX- tremity, a wiper 8, here shown as having the specific character of anelongated, somewhat downwardly bowed brush. It will be observed that when shaft 6 is rotated, the wiper l2 normally rotates in a definite horizontal plane, but the horizontal plane of movement thereof may, since the shaft 6 admits of being longitudinally adjusted, be somewhat varied, and for a purpose which will be hereinafter more particularly explained. The shaft 6 is further provided, at its upper extremity, with a hand-piece or knob 9, between which and the crosspiece 4:, there is disposed a spiral spring 10, which encircles said shaft and tends at all times to elastically hold the same at the limit of its upward, longitudinal movement. Any appropriate means may be employed for limiting the upward longitudinal movement of shaft 6, although to this end I purpose to reduce the upper portion of said shaft, thereby providing the same with a shoulder 11, which normally engages the bracket 7, at its under side, all substantially as clearly indicated in the drawings.

12 denotes a secondary wiper-shaft, which. bears at its lower end in the cross-piece 5, and at its upper portion in a bracket 13, securedto, and projecting inwardly from, the upright 2. There replaceably conjoined with the shaft 12, at its upper extremity,

wiper 11, here shown as having the specific character of an elongated, somewhat upwardly oowed brush. It will be observed that when shaft 12 is rotated, the wiper 14 rotates in a definite, horizontal plane; also that the respective shafts 6 and 12 are arranged in axial alinement and that one is adjustable toward and away from the other, to the end that the wipers S and Lt may be varied with respect to the distance between them.

Specifically, each of the wipers aforenamed comprises a rigid portion or back and a flexible portion, the latter taking the character of bristles, or any suitable material yielding or displaceable under pressure, substantially as illustrated in the drawings; and said wipers a1 arranged each with its yieldim portion facing the yielding portion of the opposite one. Again, each of said wipers is provided with a tongue projecting medially from the rigid portion thereof, said tongues being denoted,

respectively, by the numerals l5, l6, and being adapted, the former to enter aslot- 17, formed in the lower end of shaft (3, where it is held in any appropriate manner, as by means of the fastening screw 18, and the latter to enter a corresponding slot 19, formed in the upper end of the shaft 12, where itis held in any appropriate manner, as by means ofthe fastening screw 20. It will be observed, in this connection, that the respective wipers may be readily detached, each from its cooperating shaft, and replaced by another v: rying inthe matter of size or bowed form. 7

Attention is here called to the facts that shaft 6 may be rotated in either direction; that shaft 12 may be rotated in either direction; and that the said shafts taken together may be relatively rotated. in the same direction, and may vary in the matter of speed of rotation: and in this connection any appropriate mechanism may be employed to arcordiim'ly actuate the shaft 6, or accordingly actuate the sha G and 12 jointly.

For rotating the shaft (2 in a definite direction I purptve to maltruse of a train of gearing which will now be de cribed:

denotes an upright bearing-piece, arranget'l at one side of the tank aforenamed and spaced somewhat away from the adjacent wall thereof; and 21 denotes an initial driving-shaft, journaled in said wall and the bearing-piece aforenamcd, and projecting somewhat outwardly beyond the latter to receive any appropriate device, as the pulley 23, or crank 2i, whereby power and motion may be primarily imparted to said shaft.

25 denotes a driving spur-wheel, fast on the shaft 21, between the bearing-piece 22 and the wall of "the tank aforenamed adjacent thereto, and in mesh at all times with a pinion in, fast on a counter-shaft 27, the latter turning in the bearings 28, 2t), and having fixed thereon, at its inner end, a bevel-wheel 30, in mesh at all times with the bevel-pinion 31, fast on the intermediate, vertical shaft 252, the'latter bearing at its lower end in the cross-piece 5, and at its upper end in the cross-piece 4. There is also firmly mounted on the vertical shaft 32, above the bevel-pinion 31, a spur-wheel 33, which is in mesh at all times with a spurpinion 334:, preferably having a hub as indicated in Fig. 2, bearing in the cross-piece l, and disposed on the wiper-shaft 6 in a manher to turn therewith as a unit, and at the same time permit longitudinal adjustment of said shaft independently thereof. In this connection the shaft 6 may be flattened at one or more sides thereof, and the central opening in said pinion, and its hub, correspondingly shaped, substantially as indicated in the drawings. it will accordingly be seen that upon power and motion being imparted to the driving-shaft 21, such power and motion will be transmitted to the wiper shaft (3, through the medium of the intermediate train of gearing above described, the wiper 8 being accordingly rotated. Xow, to the end that the wiper 19 may be correspondingly rotated, I firmly mount on the vertical shaft 32 an additional spurwheel 35, which is in mesh at all times with a spur-pinion 36, fast on the wiper-shaft 12.

It is desirable that means he provider whereby a dish, or analogous utensil, may be inserted into, and withdrawn from the plane of movement of the wiper 8, or inserted simultaneously into and withdrawn from the respective planes of movement of the wipers 8 and 11; and to this end I purpose to make use of a dish-carrier, clearly shown in Fig. 5, consisting of opposite connected side and end pieces, and as a whole adapted to engage. slide along and rest on the opposite rails 38, 39, arranged within and at the opposite sides of the stationary, dish-carrier frame lO, the latter consisting of suitable, connected side and end pieces, and as a whole firmly connected, through the mediumof one of its side pieces, to the upright 2, and sustained at its opposite side in any appropriate manner, as by means of a support -11, rising from the cross-piece The carrier 37 is quadrangular in general form, open at top and bottom, readily displaceahle by a sliding movement from the rails 38, 39, and proyided with (llSll-SLlS-.

taining clips 42, one medially along each of its side and end pieces, and relatively disposed so as to be engaged by the margin of a dish, as ill, or other utensil, placed in the carrier 37 preparatory to cleansing the same, said clips thus serving to prevent the dish from falling through said carrier. The clips 42 may be each of any suitable general form, constructed of any suitable material, and .secured to its cooperatii'ig part of the carrier 37 in any convenient manner. The carrier 37 is pr *ferably provided with a stationary nandle -l'l, and also with a dishretainer if), the latter being preferably formed from wire, substai'itially circular in general form, hinged, as at the points ail-b, H, to the distant end piece of the carrier 37, and looped or shaped at its forward side to form integra ly therewith a handle l8, the same to be grasped jointly with the stationary handle eel, when the user desires to press the dish-retainer aforenamed downwardly in the direction of the clips 42, and accordingly hold a dish, as 13, between said retainer and siid clips, the holding force tlius applied to the dish being elastic.

Itis essential that means he provided whereby the wiper or wipers made use of, and while in operation, may be sprayed with, or otherwise subjected to, a cleansing fluid, as hot or cold water. This may be accomplished in various well known ways, as by means of a pipe 49, leading from any general supply of cleansing fluid, and haw ing a sprinkler 50 at its discharge end, said pipe and its sprinkler being arranged to direct the cleansing fluid escaping therefrom against said wiper or wipers; and to receive such cleansing fluid after it shall have served its purpose in conjunction with said wiper or wipers, any appropriate vessci or tank, as 51, may be provided, said tank having a drain-cit faucetor pipe 52.

In operation, power and motion is primarily in'ipartcd to the driving-shaft 21, and is transmitted therefrom to the wiper or wipers of the machine through the medium of the intermediate train of gearin hereinbefore described, said wiper or wipers being subjected to a cleansing fluid, as herein before explained; whcreupoi'i the o 'ierator takes the carrier 37, with the dish to be cleansed contaiited therein, and presents said carrier to and slides it, along the rails 38, 39, until said dish is brought into the plane of n'iovenicnt of said wiper, or simultanconsly into the planes of niovei'ncnt of said wipers. when both are employed. thereby allowing said wiper or wipers to act on the dish. Now, it a more severe wiping action is desired on, say, the upper side of said dish, the operator grasps the knob J and presses donwardly thereon, thereby accordingly adjusting longitudinally the shaft 6,

so as to bring the flexible portion of its wiper 8 more strongly against said dish. When the dish shall have been duly subjected to this cleansing operation, the carrier 37 is withdrawn forwardly along the rails 38, 39, the dish removed therefrom, and another dish to be cleansed substituted for the cleansed dish; whereupon the carrier 87 is again urged or slid into its normal position for service on the rails 38, 39, and so on.

It will be understood that the rails aforenamed are so relatively disposed with re spect to the wiper or wipers of the machine as to bring the dish contained in the carrier aforenamed, and when the latter is duly positioned on said rails, into the plane of movement of said wiper. or the planes of movement of said wipers when both are employed.

It will be seen that my improved machine is particularly well adapted for the purposes for which it is intei'ided. and further that the same may be modified to a considerable extent, particularly regards the mechanism availed of for imparting power and motion to the wipcr'shatt or wipershatEts, the specific character of the dishcarrier made use of, and various other minor details of the general construction, without materially departing from the spirit and principle of my invention.
